Condition resulting when a region of heart muscle is deprived of blood (which in turn deprives the region of oxygen). Intrinsic Cardiac Conduction System. Group of autorythmic (noncontractile) cells that initiate and distribute impulses and allow for coordinated depolarization/contraction of the heart. a. Because cardiac muscle is only able to depolarize after repolarization and the extrasystole cannot occur until relaxation. 1.

Extrasystole is quizlet

In a very significant proportion of people they occur spontaneously with no known cause. The decision of whether or not to treat a ventricular extrasystole depends in the first instance on the benign or severe nature of the disorder, and on whether there is subjacent cardiopathy. The results of 24-hour Holter monitoring, exercise tolerance tests and clinical and echographic examinations will define the pathological character of a ventricular extrasystole and will indicate any Hawthorn helps in the treatment of arrhythmia, accompanied by extrasystole.

an extrasystole and an extra contraction of the ventricles. The different ectopic arrhythmias are: Heart block, extrasystole, paroxysmal tachycardia, artial flutter, atrial fibrillation, ventricular fibrillation. Heart block. the term  Extrasystole. Premature contraction due to an ectopic focus (abnormal pacemaker) setting too high of a heart rate. Can be caused by excess caffeine or nicotine.

during which portion of the cardiac cycle is it possible to induce an extrasystole? what event causes extrasystole in the heart. it's caused by electrical at what point in the cardiac cycle did an extra-systole occur.

why? -A premature contraction of the heart that is independent of the normal rhythm of the heart and that arises in response to an impulse in some part of the heart other than the normal impulse from the sinoatrial (SA) node. In the cardiac muscle the refractory period of the heart lasts till the end of the contraction. Since the impulse from the extopic focus causes an extrasystole, the heart has to wait till the next natural impulse from the SA node. This is the cause for the compensatory pause. Condition resulting when a region of heart muscle is deprived of blood (which in turn deprives the region of oxygen).
